IMPROVEMENT IN GAS-REGULATORS.

Specification forming part of Letters Patent No. 158,389,

dated January 5, 1875; application filed October 16, 1874.

To all whom it may concern Be it known that I, AUGUSTUS PARSONS, ofChicago, in the county of Cook and State of Illinois, have invented anew and useful Improvement in Gas-Regulators; and I do hereby declarethe following to be a full, clear, and exact description thereof, whichwill enable others skilled in the art to which my invention appertainsto make and use the same, reference being bad to the accompanyingdrawing forming part of this specification, in which Figure 1 is aperspective view of a gas-regulator embodying my said invention. Fig. 2is a vertical central section of the same. Fig. 3 is an enlarged centralsection of the valve and seat, determining the flow of gas; and Fig. 4is a section plan on the line as m, drawn across Fig. 2.

Similar letters of reference indicate like parts in the several figuresof the drawings.

My invention relates to that class of gasregulators used on singleburners, and its ob ject is to regulate the tlow of gas; and to that endit consists in the combination, with a receptacle provided with aflexible diaphragm, through which the discharge-tube passes, of anadjustable valve arranged to adapt itself to the valve-seat,irrespective of any irregular movement of the tube, all of which will bemore fully understood by the following description and claims.

In the drawing, A represents a sheet-metal case, which is made in twoparts, and firmly bolted together at its center, as shown in Figs. 1 and2. B is a metal tube, which extends upward through the center of thecase. This tube is made tight at its lower end, as shown in Fig. 2, andis provided, at a point above the solid portion of the same, with aseries of perforations, a. O is a valve, which is loosely attached inthe lower end of the tube, and is so arranged as to admit of a slightratching movement. This valve is adapted to fit a corresponding seat, D,formed in the lower end of a depending tube, (1, attached to the bottomof the case. This tube is screwthreaded externally, by which means it issecured to the gas-pipe by means of the coupling E. F is an elasticdiaphragm, which is horizontally attached to the walls of the case atthe center of the case, as shown in Fig. 2. This diaphragm is made ofleather, or any equivalent elastic material, and is permanently attachedto the tube at a point slightly above the perforations a. The elasticityof this diaphragm is such as to admit of a slight ascending anddescending movement, by which means the tube is raised and lowered,opened or closed, the valve depending upon the pressure of gas againstthe diaphragm. G is an annular disk, which is attached to the upper endof the tube, the latter being screwthreaded externally to admit of thesame. H is the burner proper, which is attached to the disk over the endof the tube, as shown in Fig. 2. J is a receptacle, which is attached tothe tube under the disk. This receptacle is so arranged as to receiveauxiliary weights to depress the tube against the pressure of the gasagainst the diaphragm, by which means the flow of gas is determined. Thetube is provided on one side with a V-shaped key, 6, adapted to fit acorresponding groove in the upper end of the case, by which means thetube is prevented from turning when attaching or removing the disk.

In using my invention it is attached to the gas-pipe by the coupling,which allows the gas to flow into the lower chamber of indicated byarrows in Fig. 2. The pressure of gas against the diaphragm elevates thelatter, which more or less closes the valve, thereby determining thefiow of the gas.

Having thus described my invention, I claim- 1. In a gas-regulator, thevalve 0, made adjustable substantially as shown, in combination withseat D, as specified.

2. The elastic diaphragm F, arranged between the two parts of the caseA, in combination with the perforated tube B, provided with the key 6and adjustable valve 0, as specified.
